- Aims The aim of this study is to validate a diagnosis of heart failure (HF) according to the European Society of Cardiology (ESC) guidelines among patients hospitalized at Sahlgrenska University Hospital, Gothenburg, Sweden, between 2000 and 2012. Methods and results In Sweden, it is mandatory to report all hospital discharge diagnoses to the Swedish national inpatient register. In total, 27 517 patients were diagnosed with HF at the Sahlgrenska University hospital between 2000 and 2012. Altogether, 1100 records with a primary (n = 550) or contributory (n = 550) diagnosis of HF were randomly selected. The diagnosis was validated according to the ESC guidelines from 1995, 2001, 2005, and 2008, and cases were divided into three groups: definite, probable, and miscoded. In total, 965 cases were validated, while 135 records were excluded for various reasons. Of the 965 records, the diagnosis was validated as definite in 601 (62.3%) and as probable in 310 (32.1%); only 54 (5.6%) of cases had been miscoded. Echocardiography, as an objective evidence of cardiac dysfunction, had been performed in 581 (96.7%) of the definite, 106 (34.2%) of the probable, and 31 (57.4%) of the miscoded cases. Among the probable cases, the main reason they had not been classified as a definitive diagnosis of HF was lack of examination by echocardiography (63.8%). Conclusions The overall validity of HF diagnosis at Sahlgrenska University Hospital is high. This may reflect a high diagnostic validity at the time of diagnosis in the national Swedish patient register, supporting the continued use of this register in epidemiological research.

- Background and purpose - Few studies have focused on nonagenarians treated with total hip arthroplasty (THA). We investigated 30-and 90-day postoperative mortality, patient-reported outcome measures (PROMs), reoperation rate, risk factors for reoperation, and relative patient survival in nonagenarians or older.Patients and methods - 167,091 patients with primary cemented THA performed for osteoarthritis between 1992 and 2019 were identified in the Swedish Arthroplasty Register. Patients were divided into age groups based on age at time of surgery: 60-74 (n = 90,285), 75-89 (n = 75,421), and > 90 years (n = 1,385). Mortality rate, PROMs (pain- Likert scale, satisfaction-Likert scale, EQ-VAS, n = 67,553), reoperation rate, risk factors for reoperation, and relative patient survival were studied.Results - The nonagenarians had the highest postoperative mortality rate, 1.7% and 2.6% at 30 and 90 days, respectively. Nonagenarian females reported significantly lower pre-and postoperative EQ-VAS compared with patients aged 60-89 years but reported least pain and highest patient satisfaction 1 year after surgery. At 2 years the nonagenari-ans had highest reoperation frequency-2.7%-due to infec-tion (1.5%), dislocation (0.8%), and periprosthetic fracture (0.4%). Increasing age, male sex, and polished stem were associated with higher risk of reoperation within 2 years. 8-year age-and sex-matched relative survival was highest among nonagenarians (study group/matched population: >= 90 years 3.4, 95% confidence interval [CI] 3.0-3.8; 75-89 years: 1.4, CI 1.4-1.4, and 60-74 years: 1.1, CI 1.1-1.1).Conclusion - 30-and 90-day postoperative mortality and reoperation rates were higher in nonagenarians but PROM data showed least pain and highest patient satisfaction 1 year after surgery with THA among female nonagenarians with primary osteoarthritis.
